The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
What is the total count of the neutrons an protons in an atom?
The sum is called mass number.
What are the relationship between protons and neutrons in a atom?
The atomic number corresponds to the number of protons in the nucleus of an atom. It also corresponds to the number of electrons in a neutral atom. A neutral atom, you'll recall, is one where the number of electrons equals the number of protons in the nucleus of an atom. We remember that atoms often "loan out" or "borrow" electrons, so the electron count will not always equal the proton count.
What is the sum of protons and neutrons in an atom?

The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.

Mass number = Protons+Neutrons
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
What is atomic mass number minus protons?
atomic mass number - protons = number or neutrons
What particles make up the mass of an atom?
The number of protons
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
